I built this book in Sigil but had a blank white space above the cover image that I couldn't get rid of. I opened the book in Calibre, removed the cover, added it back, and converted from epub to epub, and that got rid of the white space. Then I discovered that one of my TOC entries led to a page with just the heading. Fixed that by tweaking the files.

Now I'm stumped. The first entry in the TOC is to a title page, which was working before. Now, in the Calibre reader when I click it the page is opened in my browser. In ADE it simply does nothing.

All of this is new to me and any help would be appreciated.

This is your original

Code:

<h2 class="chapter" id="heading_id_2">Title Page</h2>

Change it to :

Code:

<h2 class="chapter" id="heading_id_2" title="Title Page"> </h2>

this will not remove the height occupied, but the name will only appear in the TOC and not on the page.
